In his column about the University Research Corridor and North Carolina's comparable Research Triangle Park, Dickerson notes that Wayne State University President Irvin D. Reid, Michigan State University President Lou Anna Simon and University of Michigan President Mary Sue Coleman will go before the state Senate Appropriations Committee on Higher Education on April 20 to present the case that their universities should be recognized - and generously financed - as a Research University Corridor separate from Michigan's 12 other public universities. The Big 3 account for 95 percent of the research dollars brought to Michigan of all 15 public universities. They return $26 to Michigan's economy for every dollar state taxpayers invest in them, not counting the tuition payments.
